smIOCompatibility
Module: CME-MIB
OID (symbolic): CME-MIB::smIOCompatibility
OID (numeric): 1.3.6.1.4.1.2.3.51.2.22.3.1.1.1.18
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The compatibility status for the I/O module.
The possible values and their meanings are as follows: Unknown: This indicates a communication error for the I/O module. OK: This is the normal (good) case where there are no compatibility issues between the I/O module and the modules it is internally wired to. No Fabric: This means the other end is not populated on any of the modules this I/O module is internally wired to (e.g. this is an Infiniband switch but none of the blades it is internally wired to has an expansion card attached in the corresponding expansion slot). Attention: Indicates one of the following cases: One or more of the modules this I/O module is internally wired to is in communication error The I/O module is powered off and at least one module it is internally wired to is powered on Mismatch: Indicates one of the following cases: Fabric types are incompatible An unknown I/O module type An unknown fabric type on a module the I/O module is internally wired to.
What is smIOCompatibility?
This read-only octet string reports the overall I/O fabric compatibility status for a switch/IO module, with documented values including Unknown (communication error), OK (no compatibility issues with wired modules), and No Fabric (the other end isn't populated on any wired channel). It's a top-level health signal an admin checks before assuming a switch module can actually pass traffic to the blades and modules it's internally wired to. An admin seeing smIOCompatibility report anything other than OK for a switch module would investigate the specific blades or modules wired to it before assuming that fabric path is usable.
